Hi
I wonder if you can help.
I'm confused about how functions should work. Below is some code I write to
check my understanding.
I'm expecting two functions to be defined. Then called. One returns a random
number. The other user input (guessing the number).
I expect the return values to act like variables that I can use in a while
loop.
The programme asks for the user input then crashes. The error report says
'NameError:The name 'userGuess' is not defined.
My understanding is wrong somewhere. I thought functions would allow me to
return values I could use elsewhere without having to define them initially.
I.e. Encapsulation.
I've looked for other examples but get the same issue. I expect a function to
return a variable I can use elsewhere. Not sure how to do. In the case below
I'm not sure how I can use the work of the function elsewhere.
Advice welcome.

# coding: utf-8
import random
#guess number game
#computer generates random number
def generateNumber():
computerGuess = int(random.randrange(0,101))
return computerGuess
#get user
def getUser():
userGuess = int(input('Guess a number'))
return userGuess
#call for computer and user
generateNumber()
getUser()
#loop to check guess and report
while userGuess != computerGuess:
if userGuess < computerGuess:
print('Too low')
getUser()
elif userGuess > computerGuess:
print('Too high')
getUser()
elif userGuess > computerGuess:
print('Correct!')
#Add counter of guess later
